Just a comment about a weird thing I have noticed wrt scheduling in latestkernels.

My last two tests are 2.6.7-mm2 and 2.6.7-mm2+staircase-7.4 (plus a coupleother things, like aic updated driver). I use GLMatrix as screensaver,running with nVidia drivers (yup, tainted kernels, but both are tainted ;)).What I have noticed:- With standard -mm, as GLMatrix runs, the framerate drops even to something like a frame every couple seconds- With staircase, it keeps running smoothly at 25fps.

Something is strange in -mm. It keeps stoling cycles to the screensaver.Is this expected ?
